  Field Lengths: There may be discrepancies in field lengths or types between the data being processed and the expected structure.
  Null or Invalid Values: The presence of null or invalid values in the data can lead to marshalling failures.
  Inconsistent Data Types: If the data types in the internal table do not match the expected types in the ALV configuration, it can cause this error.

  Debugging: Use debugging tools to step through the code and identify the exact point of failure. This can help you understand what data is causing the marshalling to fail.
